HONOLULU (AP) — Hawaiian vacation over, President Barack Obama says he is energized for his final year in office and ready to tackle unfinished business, turning immediate attention to the issue of gun violence.

Obama scheduled a meeting Monday with Attorney General Loretta Lynch to discuss a three-month review of what steps he could take to help reduce gun violence. The president is expected to use executive action to strengthen background checks required for gun purchases.

Republicans strongly oppose any moves Obama may make, and legal fights seem likely over what critics would view as infringing on their Second Amendment rights. But Obama is committed to an aggressive agenda in 2016 even as public attention shifts to the presidential election.

Obama spent much of his winter vacation out of the public eye, playing golf with friends and dining out on the Hawaiian island of Oahu with his family before heading back to Washington late Saturday night.
